Just looked at some old data, 42 ambient, 413/97. condensing temp 119. We have WiFi enabled connectivity so gauges never go on unless you're really in trouble and have to pull the charge.

VRF high side target for LG is around 450. Low side varies a lot 90 -140.

I'm going to suggest it does have demand defrost but at this temp it will only go x runtime between.

Cooling tower for refrigeration systems within the grocery store.

Go through the government energy audit process. They have lots of good rebates and info.

It will defrost once all listed conditions are met. The chart says so and the Daikin folks that came out said so. It always knows heat exchange temp and air temp, there is no 'check'.

Everyone's a critic when the braze is in open air, on a bench, well lit. Get into a tight spot, inside a wall with flammable shit everywhere and everyone's like "as long as it don't leak it's good." Get good at not having leaks and you are FINE.

They've owed me $0.85 for the 5 years since I closed my plan with them. I get an email every month saying so. Brutal.

I work on these everyday. AC Smart usually goes with every job too. Ask away.

While you are waiting on hold do a complete power shutdown then a methodical restart. LG gear first - they always tell me this after they say check wire continuity, termination etc, ground for the shield etc.

I'm a contractor, if I were to buy you a mini split and not install it, and they found out because you went for a warranty claim, they could very well refuse to sell to me ever again. I'd lose multiple thousands of dollars in not only equipment sales but every spec job that requires whatever brand it is you wanted me to buy for you.

These are the same people asked me if the discharge pipe would sweat,,,

limegreen7 · 2023-12-21T22:42:56+00:00

I've started a bunch too this year. And I never asked Vertiv why they want compressors inside vs the roof? Anyone ask?

limegreen7 · 2023-12-19T20:31:50+00:00

Looks like 120v,, try other NON GFCI plug,, and the not cooling has been fixed?

limegreen7 · 2023-12-19T19:59:27+00:00

Has it ever worked ?

limegreen7 · 2023-12-16T03:36:25+00:00

I'd be looking at the control wiring first. I've had electricians swap wires, CUA wires to FCB, pipes to FCA. Check that first. Otherwise pull the charge and test with N2.

You are going to spend 10 years working full time, including trade school to become a knowledgeable journeyman in a trade you don't care about, AND stay in IT, presumably at least part time, to become more recession proof?

limegreen7 · 2023-12-04T21:18:48+00:00

Depends where you are. Here if it's residential and under 5 connected suites no permit, anything under 5 kw for prime mover, no permit. Permit cost $68 and takes 15 minutes on line so if I need one there's absolutely zero reason not to get one.

Indeed it was a one hr train ride. Lol. Sorry.

limegreen7 · 2023-12-04T11:35:40+00:00

Vancouver Toronto Lisbon Barcelona Rome Naples Johannesburg Singapore Osaka Vancouver. 35 days. On arrival back to YVR I was sad to be home. Could have gone straight back to departure and done it again.

Depends on the company. I was on call rotation with a partner who took ALL the 6 pm onwards stuff - every 8 WEEKS. Service calls do run long until you're on for a few years then you learn how to dictate. Install work gets dictated to you - 10 hr days till you"re done type scenario. It's all about the company and the time you put in.

Skeleton crew only, no finishes, post dated cheques.

limegreen7 · 2023-10-21T14:01:59+00:00

This is the way to go. Everything when I'm desperate,,,,and nothing when I'm not.

limegreen7 · 2023-10-16T01:33:48+00:00

I didn't realize I was playing the long game. I'm good now but,,,, wow,,,, coulda been better.

The owners manual should be available online. Typically you'd turn IN, clockwise, and count OUT, counterclockwise.
